Question

which is more 19 marks out of 38 or 25 marks out of 40 marks​

Answer 1

Answer:

it is the 2 one got more marks

Answer 2

Answer:

Case-I :

$19 \: marks \: out \: of \: 38 \: marks \: = \frac{19}{38} = \frac{1}{2}$

Case-II :

$25 \: marks \: out \: of \: 40 \: marks \: = \frac{25}{40} = \frac{5}{8}$

Now,comparing Case-I with Case-II -

$\frac{1}{2} \: and \: \frac{5}{8}$

LCM of 2 and 8 = 8

Changing the denominators to 8 -

$\frac{1 \times 4}{2 \times 4} = \frac{4}{8}$

$\frac{5 \times 1}{8 \times 1} = \frac{5}{8}$

$\frac{4}{8} < \frac{5}{8}$

So, Case-II is greater.

Ans. 25 marks out of 40 marks is greater.
